Magnetic Rotary Encoder IC austriamicrosystems

Rotary Encoders

austriamicrosystems offers a range of Integrated Magnetic Rotary Encoders, from 8-bit incremental up to 12-bit absolut outputs. Or in other words, from 256 up to 16384 steps per revolution with serial, analog and PWM outputs for absolute position and quadrature. A simultaneous commutation output for Brushless DC (BLDC) motors is also available. These Magnetic Rotary Encoders are an ideal solution for replacement of both absolute and incremental optical encoders, potentiometers or rotary switches in a variety of industrial, consumer or even automotvie applications requiring precise angle sensing.
